Heynote is a scratchpad and note-taking app for developers and power users.
The tool addresses the need for a persistent, easily accessible text buffer where developers can temporarily store information without friction. It solves this by providing a large, always-available workspace divided into blocks, where each block can be assigned its own programming language or format. This block-based structure enables syntax highlighting and auto-formatting tailored to the content type—useful for pasting API responses, meeting notes, or code snippets. The app includes a global hotkey option to quickly show or hide the window, keeping it accessible without cluttering your workspace.
Heynote suits developers and power users who frequently work with multiple text formats and need quick access to a scratchpad. It works well for temporary storage of JSON responses, code samples, to-do lists, or any text you want to keep separate from your main editor or messaging apps. The tool supports syntax highlighting for a wide range of languages including JavaScript, Python, Rust, SQL, and many others, plus features like math and calculator mode and currency conversion. It runs on Mac, Windows, and Linux as a desktop application.
The project shows steady, focused development with regular bug fixes and feature additions. Contributions are welcomed when they align with the maintainer's vision for the app. The tool is built on established open-source foundations including CodeMirror for editing, Vue for the interface, and Electron for cross-platform desktop deployment.
